Sim created it's own twin
I've been playing an unofficial "Legacy" family for several generations.
I've been focusing on my latest daughter, sold to a witch as a toddler for not being born a boy. She has a VERY low magic skill, having really only read the books and started a couple fires. She knows no other spells, and has one talent point. For a girl sold to a witch as a toddler, she's a great gardener but not super skilled magic wise.
So It's her birthday, she and all her friends aged up into teens. I took them all to the park to flirt and argue as teens do. It started to rain so we all ran to the bar nearby.
We are all doing homework and thinking about if we should date our middle school crush when all of a sudden my girl gets up from her chair. She walks to a corner of the room and talks to herself. A poof of smoke and sparkes later and suddenly there are two of them!!
New girl has a different first name, and different aspiration but otherwise last name, skills, likes/dislikes and clothes are all the same. She does not have the same relationships or inventory but does show up in my family tree as a sister from the same parents.
I'm so confused!
I know magic sims can duplicate things when they have that skill but themselves? And if she's a clone why does she have a different name?
Anyway I added her to my household and gave her a little make over so now she's the "evil" twin.
